Paper Abstract

Thick film resistors cannot be printed and fired to their final value because of the large number of processing variables involved. Resistors are "trimmed" to value by removing material from the conducting path. In the last decade the YAG laser has become the most important production tool for this operation. The trimming process is described, available equipment reviewed, and a procedure is described for optimizing the parameters.
